The absorption of terrestrial radiation by certain gases in the lower atmosphere is called:
greenhouse effect
Earths atmospheric greenhouse effect is produced mainly by H2O and CO2 absorbing and re-emitting what radiation:
infrared (IR)
If the earth has no atmospheric greenhouse effect the average surface temp would be:
lower than at present
On average, what percent of the suns radiation intercepted by earth and its atmosphere is reflected to space:
30%
Max temp for a particular day is 26C and the min temp is 14C, the temp daily range would be:
12*C
A place located along a windward coast will probably have what summer temps than an inland place at the same time:
cooler
A poleward moving ocean current is a what current
warm
The largest annual range of temp may be found
in a polar latitudes over land
An important reason for the large daily temp range over deserts is
there is little water vapor in the air

colder, warmer
Snow covered surfaces have a low albedo
false
The atmosphere is heated chiefly by re-radiation from the earths surface
true
The suns radiation is also referred to as a shortwave radiation
true
Clouds are poor absorbers and emitters of infrared radiation
false
Isotherms are more irregular in the Southern hemi than in the northern
false
Negative values are not possible on the celsius temp scale
